To: Ron Holt Cc: linux-kernel@vger.rutgers.edu In-Reply-To: <199608200610.AAA10372@caldera.com> Message-Id: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-kernel@vger.rutgers.edu Precedence: bulk Good question... and I, as the guy who wrote the Linux+Win95 mini-HOWTO should know the answer, but I don't. The thing with DMF is that the ONLY thing you'd be able to read is the MS-Installation stuff (office, Win95, NT, etc, etc). DMF doesn't appreciate it when you try to delete things off the media. The installation files won't delete off of them... (I've been trying to re-use all the DMF disks that MS sent me when I was a beta tester. The total is around 100!) but the only way I can use those disks is to re-format them as 1.44M. Try mounting a DMF disk on /dev/fd0 and see if it works. Win95/DOS has no special support for DMF (hence it can't delete or write to the disk, only read). There are actually a few different versions of DMF out there (two or three). This is because the folks at MS changed the format during the Win95 beta process. -Jon jkatz@in.net President and CEO, Internet Consulting by Jon Voice: +1 317.823.8221 Fax: +1 317.823.8184 9010 Anchor Bay Drive, Indianapolis, IN 46236 Personal: http://www.in.net/~jkatz Resume: http://www.in.net/~jkatz/I-need-a-job.html HOW-TO: http://www.in.net/~jkatz/win95/Linux-HOWTO.html ** On Tue, 20 Aug 1996, Ron Holt wrote: > Can Linux read DMF format floppies?
